BEER-COOLER.

SPECIFICATION forming part of Letters Patent No. 894,920, dated December 18, 1888.

Application filed July 5,1887. Serial No. 243,397. (No model.)

To all whom it may concern:

Be it known that I, ALBERT HALLowELL, of Lowell, in the county of Middlesex and Oom- Vmonwealth of Massachusetts, have invented a new and useful Improvement in Apparatus for Cooling Beer and other Substances, of which the following is a specification.

My invention relates to that class of apparatus for cooling hot wort or other liquids where the liquid is cooled by being sprayed into the atmosphere or submitted when in a iinely-divided state to the action of air; and its object is to provide an inexpensive and efficient :torni ot' apparatus for the purpose ot changing such liquids into a spray.

My invention is illustrated in the accompaing drawings, in which-d Figure l is an elevation, partly in section, of portions of a wort-cooling apparatus, showing the manner in which a number of spraying devices may be attached to a single pipe and simultaneously controlled at a single point. Fig. 2 is an elevation, partly in central vertical section, ot' one ot' the spraying devices shown in Fig. l, portions of the main supply-pipe by which it is supported and of the flushing-bar, and the flushing-cam supported by said bar. Fig. 3 is a partial vertical section ol' the ilushing-bar, the flushingcam, and the main cone-stem with a roller in .its end, and showing a portion ot" the section at the left of the line a l) ol' Fig. 2. Eig. -t is a section of the cross-bar which, carries the stem-support in which the main cone is su pported, taken at the line c d of Fig. 2.

Similar reference-numbers refer to similar parts in all of the views.

This invention resembles in some respects that which is shown iin another application of mine, Serial No. 244,155, filed July 13, 1887, and like that depends for its successful operation upon the fact that when liquids, especiallyT hot ones, are converted into a spray of fine particles, evaporation takes place very rapidly, and during this evaporation large quantities of heat are required in order to change the liquid to vapor. This heat may be absorbed from the liquid itself, the surrounding air, or from both, the temperature of the air, the liquid, or both, being lowered in the operation. It is desirable to supply large amounts ol' air to the apparatus here illustrated when it is being operated for the purpose of cooling beer, and this may be supplied in any ordinary way, such as by placing the apparatus in the open air or in a room through which large quantities oi' air are caused to )ass The s ira f'inO device here illustrated may sometimes be provided with a special means ot' supplying' air to the sp raying-head itself', like that shown in said No. 244,155, it' it is considered desirable to do so.

The sprayingl device herein described may be used either singly or in connection with several others ot the same construction, as shown in Fig. l, and an .important element of the apparatus is the means of adjusting from distance the position of the spray-producing cone, although this element may sometimes with advantage be omitted.

The sp'ray-lnloducin g device which I usually prefer to use is clearly shown in Fig. 2, where the main cone-support l is shown as provided with means by which it may be attached to a nipple, 2, that is supported by and communicates with the interior ot' the main supply-pipe Il. I prefer to form this nipple 2 upon a sleeve, 4, that may be slipped along the main supply-pipe 3 and turned thereon until the hole through the nipple communicates with a hole leading through the side of the pipe. The sleeve may then be soldered in place. By this means a supply-pipe belonging to an apparatus having several spraying heads may be easily and accurately iitted up. The main cone-support l is provided with a liquid-conduit having a valve-seat at its bottom and with means ot' supporting below said valve-scat the defiecting spray-producing cone This cone is supported by any suitable means near to the main conesupport in the example illust-rated by abellshaped piece, 6, of metal attached to and l forming a part of the main cone-support, l, and a ring, 7, attached to the bottom of the piece 6, provided with across-bar, 8, and central annular stemsupport 9. NVithin the stem-support 9 is supported the cone-stem lO, which is shown as having a screw-'thread upon its exterior surface, and a nut, ll, work- IOO ing thereon, the cone upon its upper end and the roller 12, supported by the pin 13, in its lower end. The said screw-thread, nut, and roller may sometimes be dispensed with, although the device is so much more satis Factory when they are present that l usually desire to utilize them. Below the spraying device is supported in some convenient manner by the bearin l? in the amn'u'atus shown in Vlie. 1 the flushing-bar 1li, upon which are supported the iushingLeams l-i. These cams are preferably made as shown, and l placed astride upon the edge oli' the tiushing'dlar, and jgu'ovided with screws l5 or equivalen ts therelor, by which they may be independent] y and adj ustably secured to said bar.

The bearings 1T are shown as supportedby sleeves which slip easily over the exterior surface of the main suppl y-pipe El, and are secured in place byset-screws 2l or ljiybeing soldered to the pipe like the sleeves 1, although they may be sujiported iin the proper place in any convenient way. rlhe flushing-cams are preit'- erably made with their working' ed ges rounded or sharp, as shown in Fig'. fl, an d with the roller 112 fitting' said edge, although they maybe made in any convenient shape and the roller dispensed wi th when it is desirable to do so. A cam, 111-, is adj usted with relerence to the ilushing-bar ll5byholdingthelatter si ationary in a suitable position and then, at'ter loosening,` the set-screw l5, sliplnngthe cam along the bar 1li under the roller l2 unw til the cone-stem is t'orced upward 'lar e'nrulgg'h to cause the cone to come in contact with the valve-seat7 when the cam is secured in Aplace by the set-screw 15.

The -iam ll: may sometimes be dispensed with and the cone etultrolled entirely by the nut 1.1, which is, however, intended to be used mainly .for the pn rpose o t` li uniting the amount that the valve shall be opened in llushingaml t'or the purpose ol' entirely sl'uittin olli the l'low at any particular' spraying-head when it may be desired to use the others on the main supply-pipe witlunit it, the cone 5 in that case t'orn'ling a valve. l do not, however, desire to limit myselt' to the exact li'orm ot' screw or lnut that i s shown lor th is purpose.

lt is evident that other equivalent eone-ad justers may be substituted for thenut 11 and used like that as a secondary con e-adjuster, which is independent ol the iiushing-bar lo.

The liushingbar is preferably provided with some convenient means of quiekl y movin g' it backward and forward, in the ease .illustrated the lever 18 and the link 19 being used Lt'or this purpose, although any equivalent means maybe used instead thereof. 1 do not desire to limit myseltl in the use of all forms ot my invention to the exact means ot adjustin g the spraying' device from the Vliuslung-lun', as herein illustrated and described, as I am well aware that some other forms of mechanism for this purpose may be used, one Yli'orm oli which is specifically claimed in Gase B, be-

fore re'lerred to. l am also well aware that the means of adjusting` the position oit' the coneadj usters with respect to the flushing-bar 1U, herein described, may be used in those structures where :forms olf co1ie-adjusters diltferent from the cams left are made use olf.

'lhe method ot' operation ol thisdevice is as li'ollows: lhe liquid to be cooled is by some ordinary and suitable means 't'ed into the mai n supyjily-pipe Ii in such a Amzlruner as to maintain a considerable pressure therein. The llushine'-bar is then adjust ed in such a position that they s;)raving'aanws 5 will be a slight distance Y["rom the valve-seats, when the liquid will flow out ot the sprayiiltr-heads in a line spray, which will t'all into a suitable tub or vat, 20, placed on the floor below to receive it. The lineness ot this spray and the amount oi the cooling' are controlled, as desired, by adjustin the sprayi ng' device to deli ver a `:greater or less quzintity ol.' liquid. ln order to continuously convert liquids in which are solid substances in suspension into a spray with this apparzitus it is necessary to periodically l'lush the sprayi11g-heads. This is done by quickly drawin back. the ilushing-bar, when the liquid will quickly rush in an ,augmented amount through the (uitlet ol the sprayinghead, carrying' such substances with it, after which the l'lushing-bar is qu ick ly pushed bacfh. and the liquid :loreed out in a spray again. l sometimes use a sliding' stop, 22, upon the tlushingebar lo, which is clamped in place by a set-screw, 223, or other equival ent means, in order that the flushing-bar may be (piiclily and certainly replaced. in the proper position lor cruising the cones 5 io produce a spray. l`his stop `must then be uuelaniped when it is desirable to entirely stop the flow ol' liquid at all ol the heads by the :flushingbar. lhave t'onnd thatitispossible toquickly remove enormous amounts ol' heat from hot luulies olf lliquid by passing them throughthis apparatus.

l do not desire 1o limit'mysell in the use of my invention to the exact t'orm olf all oli the paris which are herein illustrated, since the form olf several ot these parts maybe imueh changed without departing' lrom my invention.

lVhat l claim as new, and desire to secure by ALetters latent, is-
